To all whom z-'t may concern.' i i 7 i Be it known thatI, FRED S. CARR, of

Brookline, in the' county of Norfolk and. State of Massachusetts, have invented cer`j tain new and useful Improvements in Fae-l tenersfor Rugs, Carpets, &c., of which the ffollo'wingis a specification. l rIhis invention relates to means for de tachably securing a flatflexible article such as a rug or carpetto a floor or other support vin such manner that vthe flexible' article,

. which for convenience I will hereinafter ,ref

fer to as a.rug, may be quickly secured'to" and detached fromits support without liability of accidental detachment and without creating objectionable projections or protuberances at the securing points.

The invention consists in the improvements which I will now proceed to describe and claim. I

In Figs. 1 to" 13 inclusive, 'Ivhaveshown `socket members embodying my invention and 1 5 I show the socket member composed .of wire. In each case, the socket member member which may be a tack 'ornail comprlsmg a shank- 12 and a flat head \13, the

, shank being driven partly into the ysupport such as a floor 14, and with its head separated from the Hoor by narrow space suiticient to receive vthe. forked basehereinafter describedy of the socketmemben In each embodiment of the invention, the socket member 1s attached to the underside of the Irug 15 near the edge'ofthe same, the rug being represented `by dotted lines inFigs. 3 and 4.

Referring to Figs. 1 130,5 inclusive, 16 rep-f' resents the forked base of thevsocket/ memb er, the same being a part lof 'a sheet metal blank which may be of the form shown by Fig. 1, and containing a slot 17 which is open at one end of the blank and hasl a closed end constituting an abut-ment 18. -19 represents a resilient head which overhangs the base and, as here' shown. isV integral therewith, the base and head being formed in a single blank which is bent along the line Fig. 1, to cause the head to overhang the base and form a neck 20 connectingthe head and base. The head 19 is provided with a central orifice 21, the diameter of which is slightly larger than that of the stud head 13, said orifice being adaptedto receive the stud head, as shown by Fig. 4. Thehead 19 may be attached to 4the rug 15 by any suitable means such as by stitches A(not shown.) passed through the ru `and through orifices 22 formed lin margina portionsv of thehead, or by a sheet metal clamping ring 23,\having prongs 24 adapted to enter the orifices22, and to be clenched against the under side of the head 19, the ring vvbeing placed on the outer side of the' rug, as indicatedby Fig. 3. The resiliencel of the socket vmember normally holds the opposed sides of the head 19 and base 16 separated by a space lwhich is narrower than thethickness of the stud head ,13 so that said sp'ace'must be widened to permit the stud head to'be received between the socket the socket member with the stud member;` the socket member, placed on the support 14 in the position shown by Fig. 3, is moved edgewise with the rug v15 toward the stud sie .head and base. l`When it is desired to engage 21 is lifted o-ut of engagement with the stud member, the` socket member being l guided the shank 12,the outer end'of the, head 19 at the same time bearing lon the upper side' of the stud head, so that, as the movement of the socket member progresses inthe direction indicated by thearrow, Fig. 3, the outer end of the socket head rides over the o-uter surface of the stud head until the socket vmember reaches the position shown by Fig.

4, when the resilience of the socket member causes the socket head 19 tospring inwardly, the orifice 21 being at the same time caused to embrace the stud head 13. The described movement of the socket member brings' the inner end or abutment 18 of the slot 17 under the stud head'13, and to a bearingon one side of the shank 12. It will be seen that the described engagement between the socket and stud members prevents edgewise movement of the socket member in any direction. It will also be seen that the socket member may be disengaged trom the stud member by simply raising the outer end of the socket head 19 until theorifice head 13, and then moving the socket member in a direction opposite to that indicated by the arrow, Fig. 3. The described construction rovides a fastener occupying so little vertical space above the floor or support 14 that its presence under a rug 15 is not objectionable and does 'not 1n practice elevate trie rug suiicientiy'to cause a noticeable protuberance.

To limit t-he "springingof the. head `19 away from the base 16, I show the base provided with ears 40, which extend through slots 41'in the head, and are bent', as' shown by Fig. 5, to overhang the headA and form` stopsfpermitting only alimited separation of the head from the base.

,Fi 9 shows a modified form of socket mem 'er composed of a head 19 having an l orifice 21a and a forked base 16, having a slot 17 5, the head and base being made from the'blank shown by Fig. 8. The head is provided with-prongs 26 adapted to penetrate the rug and secure the head thereto.

F ig. 10 shows a different-ly formed blank, and Fig. 11 a socket member made therefrom. v The blankis composed of a central portion 27 forming the socket head and hav- 111g an orifice 2lb corresponding to the oriiice 21, and end ortions 28 which are bent under the port1on- 27, their ends being shaped to form a slot 17b corresponding to the slot 17. Theportion 27 is provided with attaching prongs 29. t

In Figs. 12 and 13 I show a modification in which the orifice 21 in the head 19 is omitted, and an embossed shoulder 25 issubstituted therefor, the construction being in' other respects thesame as that described withfieference to Figs. 1 and 2.I In. this modification, the shoulder 25 is formed to lspringinto vengagement with one side of the ranged/to bear on the opposite sideof the ,stud shank 12,' provision being thus' `made for preventing edgewise movement of the lsocketmember in any direction. In the'embodiment of' my invention represented Figs. 14'and-15, the head and base are lcom osed of wire, the base comprising-fa'neck 30, inner arms 31, 31, extending therefrom, land necks 32 connectingI the outerlportions of the arms 31 with outer arms 33, 33. The parts above enumerated constitute an equivalent of the sheet metal base 16 with its slot 17, the arms 31 constituting the sides of the slot, and the neck 30 being a substitute for the abutment 18. The socket head in this embodiment of the invention is composed of inclined portions 34, 34, of the wire connected by necks 35, 35, with the arms 33, transversewire portions 36, 36, bent'inwardly from the inclined portions 34, and Wire portions 37, 37 benty abruptly outward from the'portions 36 to lform shoulders 38, said portions 37 being inclined relatively to the ba'se and being connected by a neck 39.- The shoulders 38 constitute anequivalent of the shoulder 25. The wire socket memberl is moved into engagement with the stud member substan- -tially in the manner described with reference to Figs. 2, 3 and 4, the inner arms 31 being guided under the `stud head 13'and at opposite sides of the shank 12, and the inclined head portions 37 riding over the outer side of thestud head until the portions 3S yare in position to spring downwardlyinto engagement withv one edge 'of the stud head, theneck 30 at the same time coming to a bearingon the opposite side of the stud shank. The wire socket member maybe conveniently attached tothe rug by stitches orA a shoulder adapted to spring intoengagement with the stud head and either entirely embrace the stud head, as shown by Figs. 1 to 11, the shoulder being the wall of a circular orifice, or to bear on one side of the stud head, as shown by Fi s. 12, 13, 14 and 15. In each of said em odiments the socket member, when engaged with the stud, is not separable therefrom by horizontal Ior edgewise movement of the socket member, the locking engagement fbetween the socket and stud members positively resisting horizontal or edgewise movement of the socket member so that the members of the fastener are `not liable tov be accidentally separated by a horizontal strain on a carpet or rug secured thereby.. It is necessary before separating the members oi the tastener ments of my invention, the socket head has reame@ to move the shoulder of the socket head out-v wardly from lthe stud head, and this 'movemen-t cannot be effected by horizontal pressure of the shoulder against the stud head, but must be effected manually by springing the socket head outwardly until its shoulder is above the'stud head. This result may be conveniently accomplished by grasping the edge of the rug or carpet and raising it slightly from the floor, the socket head being slightly raised at the same time. In each of the described embodiments of the invention the stud engaging shoulder on the sockethead is adapted to be disengaged from the stud head by lifting the edge of the rug. I
